FS-4319 --resolve portaudio not always moving the active call to the top of its internal list (invalid ringing)

This reverts commit 28fd1f97.

this needs to be fixed a different way

FS-3577 : After Tamas's fixes and new logging so we can see the erl_errors, re-applying this 10ms polling interval patch that Tony committed a few months ago. Please report any issues.

I don't see this command being used anywhere. Since I don't like to touch core files unless absolutely necessary I'm reverting these two changes. I've emailed the author, Tamas, for an explanation. The other patches for FS-3432 (merged in now) appear to work fine without this commit.

This reverts commit fbcb8622.

This amends commit f8be71ac.

This still should resolve FS-4303.

What's going on here is that we need a portable way to access
strftime.  date(1posix) doesn't provide enough.  And without perl, I
can't think of a better way to get to it than just using C.  So the
logic for generating the extended revision has been moved into a small
self-contained and hopefully portable C program.

Fixes FS-4309

Why limit the query to profile_name passed. All the underlying callbacks deal with the profile not matching the one passed and will do the right thing.

FS-4303 --resolve

The fix for FS-3577 causes instabilities if multiple listeners are connected it seems. Undoing this change for now until I can figure out the root cause.

In a sofia profile, you can now set the parameter tls-timeout to a
positive integer value which represents the maximum time in seconds
that OpenSSL will keep a TLS session (and its ephemeral keys) alive.

This value is passed to OpenSSL's SSL_CTX_set_timeout(3).

OpenSSL's default value is 300 seconds, but the relevant standard
(RFC 2246) suggests that much longer session lifetimes are
acceptable (it recommends values less than 24 hours).

Longer values can be useful for extending battery life on mobile
devices.

FS-4299 --resolve regression from 23f8967c the code was not making sure both endpoints were type 'sofia' and dereferencing dingaling channel into sofia and causing memory corruption

The revision was no longer picking up the last git commit.  Instead,
it was showing the last release.  This commit appends the last git
commit hash to the last release if a git repository is available.
Further, it checks whether there are uncommitted changes in the git
repository and adds an unclean tag to the version if this is the case.

Note that currently this will append the git commit hash even on a
tagged release if built directly from a git repository.  Perhaps this
isn't such a bad thing, but if it turns out not to be desired, I have
an idea on how to squelch this without making unwarranted assumptions
about the remote layout of someone's local repository.

don't segfault after starting sofia, upon xml_open_config lookup failure for the profile from launch_sofia_worker_thread
